Dimensions
The following table gives the dimensions of various subspaces of \(M_{32}(\Gamma_1(25))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 789 | 726 | 63 |
Cusp forms | 761 | 705 | 56 |
Eisenstein series | 28 | 21 | 7 |
Trace form
Decomposition of \(S_{32}^{\mathrm{new}}(\Gamma_1(25))\)
We only show spaces with even parity, since no modular forms exist when this condition is not satisfied. Within each space \( S_k^{\mathrm{new}}(N, \chi) \) we list available newforms together with their dimension.
Label | \(\chi\) | Newforms | Dimension | \(\chi\) degree |
---|---|---|---|---|
25.32.a | \(\chi_{25}(1, \cdot)\) | 25.32.a.a | 2 | 1 |
25.32.a.b | 5 | |||
25.32.a.c | 6 | |||
25.32.a.d | 10 | |||
25.32.a.e | 10 | |||
25.32.a.f | 14 | |||
25.32.b | \(\chi_{25}(24, \cdot)\) | 25.32.b.a | 4 | 1 |
25.32.b.b | 10 | |||
25.32.b.c | 12 | |||
25.32.b.d | 20 | |||
25.32.d | \(\chi_{25}(6, \cdot)\) | n/a | 308 | 4 |
25.32.e | \(\chi_{25}(4, \cdot)\) | n/a | 304 | 4 |
"n/a" means that newforms for that character have not been added to the database yet
